(√a)^2 How do I solve this? THank you!!!

**question!**

okay. Now I'll know around when I can ask questions.. and since the time zones are different I was just wondering. My question has been answered even though it has nothing to do with hw.. but I couldn't find the answer on the website so I had to ask you here. thanks!

**question!**

What are the operating times at Jiskha when I can actually get a response within half an hour?

**Math**

you question doesn't make much sense. how can (x + 4) be the exponent from the base of 3?

**Math**

ohh... okay thanks so much! i really appreciate it. it makes sense now. ;)

**Math**

correction* 3 meters is too less room.

**Math**

Okay. That's true, 3 meters is a pretty wide space. I figured out the first dimension, it's 29.8 m. I still need the second dimension so I can figure out the area of the fenced space.

**Math**

A tennis court is 23.8 m by 11 m. A tennis club has 3 courts side by side in a fenced area. The courts have 3 m between them and 3 m around the outside. What are the dimensions of the fenced space? Please and thank you!

Can anyone help mee?

The product of -7 over 12 and a mystery number is -1 over 2. What is the number?

**Math**

What numbers have no recrpricol?

**Math**

-6 divide n = -9 and 5 over 6

**Math**

Okay. Thank you very much. I had a feeling that the answer at the back was wrong, I tried many solutions, and it didn't work. So you're probably right. :)

**Math**

The question says that the diameter is 8 cm, and then it asks to fnd the perimeter. I found the answer using your formula but when I checked the back of the book, it said the answer was 20.56 cm, not 25.12 cm.

**Math**

How do you calculate the perimeter of a half circle?

**Science**

okay. I think I understand it now. Thank you.

Why would you have to add those numbers up?

Helloo.. i got a worksheet about compounds,elements andnumber of elements. it tells me to list the elements and number of atoms found in each of the compounds and i don't understand how to do get the elements and the # of atoms in the equation.. PLease help me..!!! Common ...

correction..: how would you solve this equation? the height of a triangle is 2m more than the base. The area is 17.5m^2. Find the length of the base. it's height.. not measurement..

how would you solve this equation? the measurement of a triangle is 2m more than the base. The area is 17.5m^2. Find the length of the base.
